The Poynting vector represents the direction and magnitude of the flux in energy from an electromagnetic field. It was originally discovered by John Henry Poynting in 1884.

A Mathematical Model
The poynting vector can be derived by the equation [math]\displaystyle{ \vec{S} = {\frac{1}{μ_0}}\vec{E}\times\vec{B} }[/math] where E is the electric field vector, and B is the magnetic field vector, and μ0 is the magnetic constant.
